Revisiting Low‐Risk Thyroid Papillary Microcarcinomas Resected Without Observation: Was Immediate Surgery Necessary?

Abstract

Among PMCs that touched the TR or were located in the course of the RN, observation could be the first choice for tumors < 7 mm and those ≥ 7 mm judged as low risk for TR or RN invasion. However, for PMCs with high-risk features, immediate surgery after cytological diagnosis by a needle aspiration biopsy is recommended.
